Set up a simple network

I have 30 computers, running Win 2003. They are both connected to Linksys cable/dsl router to share

I have a small but growing office (30 people so far). We want to network in such a fashion as to have constant-on high-speed internet access, be able to email and share files internally (as through an Intranet), and be able to modem in from the outside to access files. I would appreciate anyone steering me in the direction of information that would tell us how to do this. We are so small I can't get any of the local networking firms to call me back

you are going to want to pick up a smaller comercial grade router from ebay. because one of the retail units like the wrt54g would get pretty hot under the load of serving 30 pc's you may get an ap just fr the wireless portion. but the routing should be done by a dedicated router.

also some models also include a dial in feature where they include a few modems or either dial in backup internet or dial in access from the outside.
look for specs on some of the cheaper cisco routers.
such equipment can be had for about 150 bucks if you get the right seller.
make sure that you get the right item because you dont want to have to pay shipping and cost for an item you cannot use.

i will look for suitable units. and edit this post at a later date

i found that cisco doesnt like dialup that much and leaves that part of the buisness to 3com
ok here is what you need.
